Princeton Junction Concrete Floor Crawl Space Insulation

Concrete is cold and porous which means that it was letting moisture and cold air into this crawl space. The cold air was causing cold winter drafts throughout the first floor of the home. Quality 1st Basement Systems installed a crawl space encapsulation system to seal off the space from the cold concrete floor. Under the CleanSpace crawl space encapsulation system lies SilverGlo crawl space insulation to further improve the temperature of the crawl space. This home is now healthier and warmer...and costs less to heat and cool!

Job Stories From Princeton, NJ
Basement Waterproofing in Mount Rose, NJ

A homeowner in Mount Rose, NJ was experiencing water seeping into their basement during heavy rains. This caused the water to puddle and create moisture and humidity problems in the home. The homeowner searched for possible solutions on the Internet and discovered Quality 1st Basement Systems. After reviewing their work, the homeowner decided Quality 1st Basement Systems would be the perfect fit. 

We provided a full inspection of the basement along with our recommendations. We finally helped find a solution for the homeowner and waterproofed the basement. The main components of our basement waterproofing system include the WaterGuard French Drain System and Triple Safe Sump Pump. The WaterGuard French Drain System is designed to collect water seeping into the basement and direct it to the Triple Safe Sump Pump, where it will be pumped away from the basement.

Since the installation, the homeowner has not experienced any water issues in their basement. 

Basement Waterproofing in Princeton, NJ

Quality 1st Basement Systems received a phone call from a homeowner in Princeton, NJ. The homeowner was experiencing water seepage in their basement, and they needed to find a durable solution. We sent our System Design Specialist, Joe H., to inspect the basement. Joe arrived at the home, on time, and did a full inspection on the basement. Afterward, he presented his findings to the homeowner and recommended our basement waterproofing system would be the perfect solution. 

The main components of the basement waterproofing system include the WaterGuard French Drain and Triple Safe Sump Pump Systems. Each system provides long-lasting solutions and solves the problem by keeping the basement dry all year round. In addition, our crew also installed our IceGuard System to ensure the water does not freeze over the pipes when water is pumped out of the basement. 

Since the installation, the homeowner has not experienced any other water issues in their basement. They have been fully satisfied with the services of Quality 1st Basement Systems. 

Damp Crawl Space Repair in Princeton, NJ

Water and moisture in a crawl space is never the issue a homeowner wants to experience. This homeowner in Princeton, New Jersey was experiencing a moisture issue in their crawl space. This can happen because the soil around the foundation is poorly compacted and gets saturated during heavy rainfall. This saturated soil creates hydrostatic pressure which causes water to seep through the walls and floors. A wet crawl space can have negative effects such as musty smells, pests, increased energy bills, and mold growth.

The homeowner contacted Quality 1st Basement Systems and our System Design Specialist, Greg Louis, was able to provide an inspection and help them find a solution. Upon his inspection, Greg noticed the dampness in the crawl space. Greg suggested they encapsulate the space to seal it from the earth.

Our foreman arrived at the job site and began the installation of the CleanSpace Vapor Barrier System which is thick and durable like a pool liner. The process is completed by removing any debris in the crawl space and leveling uneven surfaces and fastening the liner with drilled spikes. CleanSpace will protect the crawl space from water and moisture while having a bright and fresh appearance.

When the job was complete, the homeowner was satisfied with the outcome and the professionalism they saw on the job. They were happy to have the issue taken care of before it got worse.

Wet Basement Repair in Princeton, NJ

A homeowner in Princeton, NJ discovered water seeping into their basement. They tried to fix the problem themselves by collecting and dumping out the water themselves but the situation was far more serious. They knew they needed professional help, so they contacted Quality 1st Basement Systems. 

We scheduled an appointment for our System Design Specialist, Laszlo Lenkey, to provide a quote for the homeowner. Laszlo arrived at the home, on time, and inspected the basement. As Laszlo was inspecting the basement, he found small vertical cracks on the wall allowing water to seep into the basement. He presented this to the homeowner and suggested the best solution was to waterproof the basement. 

The main components of the waterproofing system include the WaterGuard French Drain System, Triple Safe Sump Pump, and SaniDry Sedona. With these products combined, excess water will be collected and pumped away from the basement allowing the area to be fully dry and secure. 

In conclusion, the homeowner was very happy with the installation process. Since then, they did not experience any water issues in their basement and were satisfied with Quality 1st Basement Systems.   

Extreme Crawlspace Makeover in West Windsor, NJ

A homeowner in West Windsor, NJ noticed that his allergies started acting up drastically. The homeowner mentioned to his neighbors that there was a small door that leads to another side of his home but never checked it out. The neighbors told the homeowner that it could lead to a small crawlspace that might be the problem to his allergies. The homeowner went back home and opened the small door, revealing the degusting crawlspace. It was very damp and the walls had dust and mold growing on the walls. The homeowner was completely mortified and knew that he needed to get this fixed. He told his neighbors and asked who he should call to fix this problem. His neighbors strongly recommended the Quality 1st Basements System, so the homeowner called us and scheduled an appointment for our specialist to come out and inspect the crawlspace. 

Our system design specialist went to the homeowner's home and inspected the crawlspace. Our specialist inspected the crawlspace and asked the homeowner how long it has been since the crawlspace has been maintained. The homeowner told our specialist that he has never acknowledged the crawlspace until now, so our specialist concluded that the moisture and humidity built up over the years, causing the crawlspace to become damp and disgusting. Our specialist also told the homeowner that 50% of the air that we breathe in our homes is from our crawlspaces and basements, so the crawlspace air is filtering throughout the entire home. The homeowner was completely shocked, as he never knew this before. He immediately scheduled another appointment for our specialist, and crew, to come out and insolate the air his crawlspace. 

Our crew installed our SaniDry Sedona Air System to filter the dusty and unhealthy crawlspace air. The SaniDry Sedona Air System is our single unit, high-efficient dehumidification system with air filtration. The system contains a powerful blower that circulates the air into and around the crawlspace. This made dampness disappear! Another great quality about the SaniDry Sedona is that it does not have to be installed in the room that has to be dehumidified. Our Sedona can be installed in any part of the home, and the vents help circulate the air.

Ever since the SaniDry Sedona was installed, the homeowner did not have problems with the air filtration in his home. His allergies also came to an end, making him fully satisfied and also becoming a loyal customer of Quality 1st Basements Systems. 

Leaking Basement Walls in Princeton

Homeowner in Princeton contacted Quality 1st Basement Systems due to water seepage in her basement after a heavy rainstorm. The homeowner was midway through renovating her home and decided to wait on waterproofing her basement. During the next rain storm, she had even more water in her basement which caused severe damage to her flooring. Upon inspection, Quality 1st Basement Systems determined that the basement flooding was due to water coming in through cracks in the foundation.

Quality 1st Basement Systems addressed the cracks in the foundation. To waterproof the basement, a full perimeter system was installed to drain the water out of the basement. WaterGuard is specially designed to accept water from the walls preventing the water from ever entering the basement. There is spacing along the WaterGuard system that other waterproofing systems do not have which make the system able to better accept the leaking water. WaterGuard drains to this homeowner's new TripleSafe Sump Pump, which contains three pumps so it always works. One of the pumps has a battery back-up in the event of power outages.

To prevent any water vapor from entering the basement walls, Quality 1st Basement Systems installed a CleanSpace Wall Liner. CleanSpace is a white, 20 mil thick plastic liner that is fitted along the walls sealing off the rest of the basement. CleanSpace will last as long as this Princeton home and keep the basement dry. The bright, white coloring of CleanSpace also really brightened this unfinished basement. This basement is now clean, dry, and humidity-free!

Basement Waterproofing in Princeton

A homeowner, Lucy S., in Princeton called Quality 1st Basement Systems worried that the dark spots on their basement wall were mold. The home had a cinder block foundation, and there was a musty smell in the basement.

System Design Specialist, Dan McNally, went out to evaluate the home. He was able to asses the problem, determine a solution, and suggested that the homeowner upgrade their present dehumidifier to the SaniDry Dehumidification System. Most dehumidifiers on the market are just not powerful enough to work for the entire basement space like SaniDry. BrightWall wall panels would keep the  humidity and water vapor from passing through the walls into the space, preventing further mold growth. Dan also recommended replacing a window that was leaking water into the basement.

Foreman Jonathan Neira and the Quality 1st crew arrived right on schedule and quickly had a new window and the BrightWall paneling installed. The SaniDry Dehumidifier was set up to keep the air in the basement clean and dry.

The homeowner is very happy with the bright, clean look of her basement, and the musty smell is now gone. She tells all her friends and family to call Quality 1st Basement Systems!

Flooded Princeton Basement Waterproofed and Refinished

A Princeton homeowner reached out to Quality 1st Basement Systems in regards to flooding in his basement. The flooding occurred during heavy rains. The homeowner noticed that the frequent flooding had caused damage to his wood flooring and the sheet rock on his walls.

Quality 1st Basement Systems diagnosed the problem as ground water seepage. When it would rain, the ground surrounding the home would become so dense with water that the water would enter the basement through the walls and floors. To waterproof the basement, Quality 1st Basement Systems installed WaterGuard around the perimeter of the basement to ensure that the water could no longer enter the basement. WaterGuard was attached to a SuperSump Sump Pump to pump the water away from the basement.

To return this basement back into a fully-functional and finished room, Quality 1st Basement Systems installed 1/2 EverLast Wall Panels. EverLast panels are made from inorganic materials (will never grow mold), washable, and completely waterproof. MillCreek flooring was installed to finish the floor of the basement. MillCreek is completely waterproof and looks just like wood! If this homeowner has any water vapor or plumbing leaks, the walls and floors will be protected!
